Approximation of an Surface S(u,v)
(and eventually associate 2d Curves) defined
by section's law.
This surface is defined by a function F(u, v)
where Ft(u) = F(u, t) is a bspline curve.
To use this algorithme, you have to implement Ft(u)
as a derivative class of Approx_SweepFunction.
This algorithm can be used by blending, sweeping...

| Perform the Approximation [First, Last] : Approx_SweepApproximation.cdl Tol3d : Tolerance to surface approximation Tol2d : Tolerance used to perform curve approximation Normaly the 2d curve are approximated with a tolerance given by the resolution on support surfaces, but if this tolerance is too large Tol2d is used. TolAngular : Tolerance (in radian) to control the angle beetween tangents on the section law and tangent of iso-v on approximed surface Continuity : The continuity in v waiting on the surface Degmax : The maximum degree in v requiered on the surface Segmax : The maximum number of span in v requiered on the surface Warning : The continuity ci can be obtained only if Ft is Ci | |
